9.15.3 LSI System Calibration
a. Standard Calibration
To calibrate the LSI, certain conditions must be met:
• The sensor must be installed at least 6 hours before
beginning calibration.
• The machine control system must be powered on for
at least 10 minutes before calibration.
• The calibration shall be conducted with the standard
carriage and forks attached and weights as
necessary.
• If the machine is equipped with outriggers, they shall
remain up for the calibration procedure.
• The machine must be on a level surface with the
wheels steered straight and park brake off, with
straight driving over a distance of at least 2 m (6.5 ft)
being the last movement before entering a
calibration point.
• The calibration must be completed within 30 minutes
after starting procedure.
Calibration Procedure:
1. With ignition key in OFF position, press and hold
TEST button on LSI display and turn ignition key to
engine START position. Release the ignition key
when engine start is achieved, but continue to hold
TEST button on LSI display until the led power
indicator on LSI display begins to flash
(approximately 2 seconds). Release TEST key
within 2 seconds of power led flashing.
2. The lower green led of the scale should be on
constant. Position the machine with empty
attachment with boom level and fully retracted, forks
level (not contacting ground).
3. Press the TEST button on the LSI display and
release. The lower green led should flash for
approximately 8 seconds while the calibration point
is read. Following a successful calibration of the first
point, the buzzer will sound for 2 seconds, the green
led will be turned off, and the top red led will be on
constant.
4. Position the machine (using weight on the
attachment) such that the rear axle weight in the
following table is achieved
.
5. Press the TEST button on the LSI display and
release. The top red led should flash for
approximately 8 seconds while the calibration point
is read. Following a successful calibration of the
second point, the buzzer will be on constant, the red
led will be turned off, and the green power led will be
on constant.
6. Turn the ignition key to OFF. LSI is now calibrated.
b. Field Calibration
To calibrate the LSI, certain conditions must be met:
• The sensor must be installed at least 6 hours before
beginning calibration.
• The test weight matches the model being calibrated
in the table shown on page 9-39.
• The calibration shall be conducted with standard
carriage and forks attached to the machine.
• If the machine is equipped with outriggers, they shall
remain up for the calibration procedure.
• The machine must be on a level surface with the
wheels steered straight and park brake OFF. Drive
the machine forward over a distance of at least 2 m
(6.5 ft) before entering a calibration point.
• The calibration must be completed within 30 minutes
after starting procedure.
